STUrijnivG-iaox.`

Be ,it known ythat we, WILEY lV. Yonne' and AUGUST A.'Coornmbothcitizens ofthe United States, andresidents of Milwaukee,

in the lcounty of Milwaukee -and Stateof lisconsiin and ofBut-ler,-in'tlie countyof Milwaukee and State oflwisconsin,'respectively, have invented certain newfaiidri'iseV ful Improvements inStaining-Boxes; and we do herebydeclare, that 'the following is?v afull, clear, and exact description thereoff.:

The primaryobject of' oui'A invention is to provide a simple,economicziland effective fitting for stuffing'boXe's tvo/be used inforining a tight joint between a fixed head y"and amovable piston thearrangement and con-t struction 'beingefsncli that the several def`tachable fittings ybel ,dismantled` yfrom about the piston or rodwithout removal of the latter from its head or cylinder, ywherebvany orall of suclifittings can be quickly replaced in case` of repen-sand whenso replaced the several parts form a compact,

rigid andtightly packed joint.

ithy the above lob'ect in view the invention consists', in certainpeculiarities'of conf struction andl combination of parts as set forthhereinafter with reference' to the aeeompanying `drawings andsubsequently claimed. f a

In the ,drawings Figure .1 represents a longitudinal sectional view'of afragment of a cylinder head having a reciprocative piston-rod mountedtherein and',provided with a fitting embodying the` features of our"invention, parts ofthe samebeing broken away to more clearly illustratecertain structural features with the .plane of the sec-y tion indicatedbyline 1-1 of Fig. 4; Fig. 2, a similar sectional view, the sectionbeing indicated by line 2 2 `of Fig. 4; Fig. 3, a detailed cross-sectionof the fitting, the section being indicated by line 3-3 of'Fig. 1.;

Fig. fi, a. detailed crossesection indicated by line -Ltof Fig. 1, andFig. 5, a detailed face yview of a semicircular collar constitilting oneof the fitting members.

Referring by characters to the drawings, 1v

represents a portion of the head of a cylinder that may form part of acompressor or prime mover, the head beinl provided with the ordinarytype of stu ng box 2 into which is fitted a piston-rod 3. Thestuffing-boris also provided with the usual packing e that is fittedabout the rod. The 'packing is held in place by a follower orspecification yof Letters Patent.

Atangula'relug 6 memben "w e 'glandthat is formed in two semicircularsections and 5'., the,samejbeingsplit upon aA longitudinal,divisionlineV as shown. .The

.member o of the gland at its division line isprovidedwitha'rectangularrecess 6 adjacent to one'jend for the reception of arecthat projects from the other locked; there being a dowel pin 71extending 'from one'of thdrecessswalls 6 that is ar-y Irangedto be"fitted into a dowel-receiving raient-eu Mar. 25,1913. t Y `Applicationled January 9, 1913. j Serial No. 740,913.

rfeby said members are inter l l aperture 7,'which aperture is formed inthe y projectingl1`1g"`6.-.y The inner end of the 'gland is' alsoprovided with a packing ring Aengaging flange 8 and a' pair of `annularshoulders 9, 9'@ thatare spacedv adjacent- :to

its louter end, which shoulders are l spacedapartto form an annulargroove, the'shoulders of the split members being arranged to coincidewhen Asaid members are assembled Vto form rings.

Fitted between the shoulders?) and 9 arel apair of semicircula'r collars10, 10',` which Vcollars are provided with ears 12, 12, 124,

12,respectively, that are of an approximate thickness equal to oneehalfof the collar- 'f thickness. in cross-section, the said ears ,beingapertured and whenassembledy overlap eachother, whereby their aperturescoincide to form seats for retaining bolts 13, 13. which bolts are inthreaded union with the stufiing-box as best shown in Fig. 1.

From the foregoing description itis apf parentthat should it bedesirable to renew or tighten the packingI between the pistonrod andstuffing box that the retaining bolts can be manipulated for effectingthe desired result and should it be desi-redto renew the gland or anypart of the removable fixtures constituting the joint, it is alsoapparent that the ent-ire mechanism can be disorganized by removing theretaining bolts 13. Should the retaining bolts be withdrawn from theapertured ears of the semicircular collars, the said collars can bereadily removed and thereafter the two-part gland can also be removedfrom about the shaft. anda new two-part gland substituted therefor or asingle section of said gland, which may have become worn 'or broken, canbe thus replaced. After replacing of the gland members in theirinterlocked position the semicirculur collars are then inserted be tweenthe. shoulders 0 and 9 and secured b v adjusting the bolts to thestufiingbox und thus the gland in its entirety is completely and readilyinserted in place in a few moments. It is also apparent that should oneof the collar members become broken or worn that similar vmembers can besubst-ituted for those broken in the same manner as described inconnection with the gland portion. Attention is also called to the factthat owing to the stepped or interlocked longitudinal joint between thefollowermembers 5 and- 5 that said joint is practically steam-tight andthat the members are held securely together at their inner ends by thedowel-pin and that the outer ends of said members are heldsecurelytogether by.

engagement with the semicircular collars. vIn practice it has been foundthat should a unitary gland become Worn or broken much annoyance andloss of time and expense will result, due to the fact that should thegland, constituting part of a prime mover be broken, such breakage wouldnecessitate a shut-down and in order to renew the broken part, the shaftor piston-rod must lbejdismantled so as to insert a unitary gland,annular shoulder extending from its face,

means for interlockingthe split gland members, and a pair ofsemi-circular collars engageable with the gland shoulder, the pair ofcollars being provided with registered bolt receiving ears.

2. In a joint for a piston and cylinder head, the head being providedwith a stufiing box extending therefrom; the combination of alongitudinally split gland having a pair of annular shoulders extendingtherefrom'to form a circular recess at one end, a pair of semicircularcollar members engageable with the gland between the shoulders,apertured ears extending from the collar members, and retaining boltscarried by the stuiling box engageable with the ear apertures. i

3. A` fitting for smiling-boxes comprising a longitudinally split gland,one of the split members being provided withanend recess,

the opposite member being provided with a,

lug engageable with the recess, a pin for f locking the lug and recesstogether, a shoulder extending from the gland member adjacent 4to theouter end, and a bolt-receiving collar engageable with the glandshoulder. In testimony that we cla-im the foregoing we have hereunto setour hands at Butler in the county of Milwaukee and State of VVisconsinin the presence of two witnesses.
